Nice numbers. Do you have a boost plot? Curious how the curve is....

Very nice. Was the second car an 8 or a 9?

Looking good!

Congrats Sean! Looking forward to riding along with the new setup!!

The first graph is really nice, now i wonder if the difference is due to the cams or 3port vs mbc or e9 vs e8 maybe? Would like to know the details.
Still some great number on 93, is there e85 plans for any of those cars?

The first car has an o2 dump where the second one does not mention an o2 housing at all :confused:

I'm not planning on E85 anytime soon, mostly because of availability where I live. I'm incredibly happy with the results as is{thumbup}

Dual map man! Thats what I am gonna do. E85 for when we go to the track, pump for dd status! :D

Can you tell me at what rpm do you see 25psi in 3rd? I got ef2 to replace my green which I hqvent installed yet but would like to know how the turbo spools and come on the boost.

Great results.. So on E85.. 475ish?

No sorry, the first car was still on a stock map sensor. The second car was tuned a couple months ago and I don't hold onto logs that long.

It was an 8.

The second car was on a stock O2 housing and exhaust manifold, the first car had a O2 dump and ported exhaust manifold.

In Sean's car which is the first car, we saw 25 psi @ 3500-3600 in 3rd gear.


twnty100drummer, glad you're enjoying the car and let us know if you need anything {thumbup}:beer:

How does it feel comparing to stock turbo?

those are awesome numbers. These EF turbos are aweome. Its dyno plots like these that make me anxious to see what ill make on my setup. im going for 25 psi as well, but i have an EF3, with a 2.3, and tuned on E85. Id be happy seeing a 400 number.:)

It hits a little harder, but unlike the stock turbo, it pulls all the way through the power band. I don't feel it die off up top!
